The ministg package

ministg is an interpreter for a simple high-level operational semantics for the STG machine. The
semantics is taken from the research paper "Making a fast curry: push/enter vs. eval/apply
for higher-order languages", by Simon Marlow and Simon Peyton Jones. It provides the option
to trace the execution of the interpreter, rendering each step in a HTML file. This is useful
for understanding the behaviour of the STG machine, and also useful for experimenting with
changes to the machine. It also supports an experimental call stack tracing facility.
